TestFlight is an online service for over-the-air installation and testing of mobile applications, currently owned by Apple Inc and only offered to developers within the iOS Developer Program.[1][2][3] Developers sign up with the service to distribute applications to internal or external beta testers, who can subsequently send feedback about the application to developers.[4][5][6] The TestFlight SDK additionally allows developers to receive remote logs, crash reports and tester feedback.[7]

TestFlight initially supported testing of Android and iOS applications, but since March 2014, Apple has retracted support for Android.[8][9] As of 2015, applications must be published for TestFlight using Xcode, and testers must be invited using iTunes Connect.[4] After invitation, up to 25 internal testers (with up to 10 devices each) and 10,000[10] external beta testers can download and test the application build. Up to 100 apps can be tested at a time, internally or externally.[4] Testers may be grouped and separate builds created for each group.[4] The TestFlight application for iOS notifies testers when new builds are available, features to focus on, and enables sending of feedback.[4]


TestFlight was founded by Benjamin Satterfield and Trystan Kosmynka on December 23, 2010, and was designed as a single platform to test mobile applications on Android and iOS devices.[11][12] It was acquired by Burstly in March 2012, and thereby gained the resources necessary to launch TestFlight Live.[11][12] TestFlight Live enabled developers to receive install rates, purchase rates and other monetization data from final builds of the application, even after beta testing concluded.[11]

In 2011, Burstly raised $7.3 million from Upfront Ventures, Rincon Venture Partners, Softbank Capital and others.[9] Apple Inc. acquired Burstly in February 2014, and terminated support for Android as of March 2014.[8][9] Apple also shut down FlightPath (a mobile analytics solution and a replacement to TestFlight Live) and SkyRocket (a mobile application monetization platform) the same month.[9][13]
